Yukon GM 10.5" & 11.5" Full Float Rear Axle Bearing & Seal Kit
YUKAK GM11.5
The Yukon Rear Axle Bearing and Seal Kit is designed to restore proper wheel-end support and sealing performance in GM 10.5" and 11.5" full-float rear axle applications. Built with high-quality bearings, races, and seals, this complete service kit helps eliminate wheel-end play, reduce bearing noise, and prevent gear oil leaks caused by worn factory components. Designed to service one side of the axle, this kit is ideal for heavy-duty towing, work trucks, fleet vehicles, and off-road applications running oversized tires and increased loads.
GM 10.5" and 11.5" full-float rear axles are commonly used in Silverado and Sierra HD trucks where wheel bearings carry substantial vehicle weight and towing stress. Replacing worn inner and outer bearings along with races and seals helps maintain proper hub alignment, reduce heat buildup, and improve long-term axle reliability under demanding hauling and off-road conditions.

Tech Insight
Full-float rear axles use large inner and outer wheel bearings to support both rotational load and vehicle weight, making proper wheel-end maintenance critical in heavy-duty truck applications. Worn bearings can create wheel-end movement, excessive heat, and premature hub or spindle wear if left unserviced.
Replacing bearings, races, and seals together ensures proper preload and long-term durability. During installation, inspect the spindle and hub bore for wear or discoloration caused by overheating to prevent premature failure of the new components.
